Makikihi River at Milnes Road

The Makikihi River is a small braided river draining the hills of the Waimate District. 

This site is located downstream of the bridge on Milnes Road. The riparian vegetation is primarily exotic species with intensive farming encroching on both sides of the river.

Ecological data for this site

This dashboard shows the result of macroinvertebrate sampling at this site.  It displays three measures, macroinvertebrate community index, taxanomic richness and percent EPT

If 'N/A' is showing, there are not enough data to calculate a 5-year median.  You can select the 'Show more information+' box under each measure to see the available historic data.

  • MCI

    Quality class based on MCI score
    The median of the last 5 years of data

    {{MciText | uppercase}}

    The Macroinvertebrate Community Index uses aquatic macroinvertebrates to assess the health of streams in New Zealand.

    What do the icons mean?

    EXCELLENT
    MCI score of more than 119. Streams in excellent ecological condition. Indicative of excellent water quality and/or habitat conditions.
    GOOD
    MCI between 100 and 119. Streams in good ecological condition. Indicative of good water quality and/or habitat conditions.
    FAIR
    MCI between 80 and 99. Streams in fair ecological condition. Indicative of only fair water quality and/or habitat condition.
    POOR
    MCI less than 80. Streams in poor ecological condition. Indicative of poor water quality and/or poor habitat conditions.
  • Taxonomic richness

    The median of the last 5 years of data

    {{medians.TaxaMedian || 'N/A'}}
    Taxonomic richness is the number of different taxa present in an ecological community identified to the best possible level.

Can I trust this data?

The Cawthron Institute has worked alongside regional councils to verify the processes and methods used for macroinvertebrate data collection, processing of the data in the laboratory, quality control in the field and laboratory and the statistical analysis and interpretation of the results presented.

Data Collection

Macroinvertebrates are sampled at this site as part of council's stream health monitoring programme, as recommended by proposed national guidelines.

Sampling - Frequency

Macroinvertebrate sampling is done annually or more frequently at this site as recommended by proposed national guidelines. Therefore, data shown here follow current best practice guidelines.

Sampling - Protocols

This site is a hard-bottomed site and appropriate sampling protocols have been applied.  Data shown here have been collected using current best-practice.

Sampling - Habitat

Macroinvertebrate sampling is done in all meso-habitats (i.e., pool, run and riffle), rather than just in riffle habitat, as current guidelines suggest. All-habitat sampling provides a more comprehensive description than riffle-only sampling of the invertebrate community at a stream site. However, comparisons made between macroinvertebrate data collected in all habitat and data collected in just riffle habitat need to be treated with caution.

Sampling - Stand-down period

This council does not collect any macroinvertebrate samples for up to two weeks after a flood greater than three times the median flow as recommended by proposed national guidelines. Therefore, data collected at this site is following best practice.

Processing - Protocol

Samples at this site have been processed following protocol P2 which is recommended by proposed national guidelines. However, the individual count number has been reduced from 200 to 100 (with a scan for rare taxa).  Data processed at this site are therefore not following best practice and conclusions based on this data need to be treated with caution.

Quality Control - Field

Data collected at this site had some form of field quality control done.

Quality Control - Lab

Data processed at this site has had one of the three Laboratory Quality Control Protocols (i.e., QC1, QC2,Q C3) applied. Data shown here is more robust than data with no laboratory QC applied.
